Introducing a rare neckband-type Bluetooth earphone with an inner-ear design that doesn't block your ears, a new arrival in the industry! 【Ideal for Exercise ◎ Comfortable Fit ◎ Unique Patented Technology】 Successfully achieved a 20% reduction in power consumption compared to previous models, improving issues such as sound leakage and skipping by about 50%. A single full charge provides up to 15 hours of music playback. Fast charging allows for about 1 hour of music playback with a 5-minute charge via the USB-C port. Equipped with the latest Bluetooth 5.0+EDR standard, offering improved connectivity, communication speed, and range. 【Inner-Ear Design & Stable & Magnet Equipped】 To improve the discomfort of conventional canal-type earphones, we designed an ultra-lightweight earphone, weighing only about 6g per ear, and developed a gentle inner-ear design that fits perfectly in the ear. Combining soft and durable shape-memory silicone material with the earphone body connected by a thin cable provides excellent stability around the neck and shoulders, reducing the burden on the ears. The cable uses a tangle-resistant flat cord. The design also carefully considers the balance around the neck. Magnets are installed in the left and right earphones; when brought close together, the earphones immediately attach to each other, making it convenient to wear them around your neck like a necklace when not in use. 【Hi-Fi High-Quality Sound & 40% Volume Level Recognition & Multi-Point】 Committed to sound quality, we have a hybrid structure that combines two drivers: a dynamic type and a planar magnetic driver, based on our unique design. You can enjoy high-quality sound by clearly separating the bass, mid-range, and high frequencies. Convenient multi-point pairing is possible for business use. 【Fast Pairing Technology & Easy Operation & Excellent Calls】 With automatic pairing technology, it automatically connects from the next time after pairing with your smartphone for the first time. Easy operation of music playback/pause, volume adjustment, call start/end/reject/redial/Siri, etc., via the remote control. Equipped with a high-sensitivity microphone, it suppresses microphone noise during calls and reduces ambient noise, making the other party's voice easy to hear and achieving clear calls. 【IPX7 Waterproof & Practical Earphones & Package Contents】 The Bluetooth earphones have a waterproof design, with waterproof and sweat-proof performance that can withstand sweat during sports, humidity in the bath, and use in light rain. 124-398
